Between 25th and 28th of February, Mobile World Congress 2019, the biggest congress on telecommunications in the world, is being held in Barcelona. Almost all technological advancements, which are being deployed or will be deployed in the coming years, are presented by outstanding companies from all around the world.
The congress is strongly focused on the new 5G network and how the network should be deployed, so that it is not disruptive to current LTE/3G/WiFi networks. In fact, there is a strong push on networking self-management and integration of all wireless accesses to one managed access, so the future business will be on one access and several services, all of them softwarized at different levels.
Even if 5G itself is at the core of the congress, there are many companies showing applications to be deployed over the 5G network, with Virtual Reality/Augmented Reality and autonomic vehicles being the most impressive ones. Automatic robotics is being widely deployed with communication in the 5GHz and 5G mmWave bandwidth space. Aerial, maritime, and terrestrial autonomic vehicles have been deployed using the vehicle-to-infrastructure (also called vehicle-to-everything) v2x standard, which is in charge of controlling vehicles securely. This is in line with the vision of the physical world being beyond the control of a single vehicle.
There are many companies deploying advanced interfaces that ease human interaction with the digital world (say, with robots), with data (information everywhere), and even with the physical world, like interfaces for communicating with animals, integration of robotics in the human body, etc.
Another major area of interest is cybersecurity. This includes not only security issues of networking hardware, a topic that recently became relevant all over the world, but also integration of cybersecurity in small components and software, with related ethical dilemmas (e.g., how the human being should ultimately control the robots).
In conclusion, 5G, AI, interface-to-all, and security are the key topics at the most important commercial congress on telecommunications.
